[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool receiver provided in a shank provided on a spindle.

[0002]

2. Description of the Related Art Conventionally, an appropriate tool 3 is mounted on a shank 5 fitted to a spindle 2 of a cutting machine by a chuck device 1 (the same components as those in the present embodiment are denoted by the same reference numerals). ).

When the tool 3 is mounted on the shank 5, it is necessary to make the degree of protrusion of the tool 3 from the shank 5 appropriate. Therefore, the tip of the tool 3 is flattened in the female screw hole 5a of the shank 5. The formed male screw body 4 is screwed.

Accordingly, the male screw body 4 is appropriately screwed into and out of the female screw hole 5a, and the proximal end face 3a of the tool 3 is fixed to the male screw body 4a.
The tool 3 is brought into contact with the flat surface at the tip end to obtain an appropriate degree of protrusion of the tool 3.

[0005]

However, when the accuracy of the base end surface 3a of the tool 3 is poor and the base end surface 3a is an inclined surface, the tip of the male screw body 4 is a flat surface, so that the chuck device 1 is not used.
When the tool 3 is clamped with, the tool 3 is inevitably mounted correctly in the shank axis direction of the shank 5,
Naturally, the running of the tool 3 occurs during the operation of the cutting machine.

It is a technical object of the present invention to provide a tool receiver which solves the above problems.

[0007]

The gist of the present invention will be described with reference to the accompanying drawings.

When the tool 3 is mounted on the shank 5 provided on the spindle 2 using the chuck device 1, the base end surface 3a of the tool 3 comes into contact with the tool 3 and is screwed into and out of the shank 5 in the axial direction of the shank. Possible cylindrical male screw 4
Screw body 9 screwed to the tip of the male screw body 4
It is fitted into a spherical recess formed at the tip of the body 9,
A spherical surface conforming to the spherical recess is formed and a flat surface at the tip
And a screw abutment 6 at the base end.
The male screw body 4 is formed with respect to the male screw body 4 by the formed square hole 9a.
4 is screwed from the base end direction, and the male screwed body 4 is at the front end facing position.
The shank 5 is formed by the notch groove 4a formed in
The present invention relates to a tool receiver which is configured to be screwed from the tip direction of the link 5 .

[0009]

The flat surface at the tip of the tool abutment 6 is aligned with the screw 9
Proximal end portion 3a of the example tool 3 for rotating the tool 3 be inclined surface is accurately mounted to the shank axis direction of the shank 5 Te.

BRIEF DESCRIPTION OF THE DRAWINGS The drawings illustrate one embodiment of the present invention and are described below.

A shank 5 is fitted to a spindle 2 of a cutting machine by taper fitting, and a tool 3, in this case, a drill, is inserted into a tip of the shank 5 by a chuck mounting 1. A male screw body 4 is screwed into the shank 5, a small-diameter screw body 9 is screwed to the tip of the male screw body 4, and a spherical tool is attached to the tool contact portion at the tip of the screw body 9. A concave portion is formed, a spherical surface matching the spherical concave portion is formed in the spherical concave portion, and a tool contact member 6 having a flat end at the tip is fitted therein. It is provided in a state in which the head can swing. Note that the male screw body 4 and the screw body 9 may be formed integrally. Reference numeral 4a denotes a male screw 4 for the shank 5.
A notch groove formed in an opposed state for screwing in and out, 7 is a collet chuck, 8 is an outer cylinder, and 9a is a hexagonal square hole for screwing the screw body 9 into and out of the male screw body 4.

In this embodiment, the male screw 4 in the shank 5 is adjusted to an appropriate position in advance, and then a drill is inserted into the shank 5 so that the base end face 3a of the drill is adjusted. The drill is brought into contact with the flat surface at the tip end of the tool contact body 6, and the outer cylinder 8 is tightened to press the drill.

At this time, since the tool abutting member 6 is provided so as to be able to swing the head, for example, even if the base end face 3a of the drill is inclined due to poor accuracy, the tool abutting member 6 is not inclined. Since the head is swung appropriately following the surface, the drill is accurately inserted in the axial direction of the shank.

[0014]

[Effect of the Invention] The present invention is configured as described above.
The tool can always be arranged in the correct state, and thus the tool receiver can perform the correct operation accordingly.
